Lub raj tooj liab yog tsim los ntawm 99.9% ntshiab tooj liab thiab me me alloying ntsiab lus thiab ua raws li cov qauv ASTM luam tawm.Lawv yog cov tawv thiab mos, lub ntsiab lus tom kawg hais tias cov yeeb nkab tau raug annealed kom soften nws.Rigid hlab yog txuas nrog capillary fittings.Hoses tuaj yeem txuas rau lwm txoj hauv kev, suav nrog compression fittings thiab flares.Ob leeg yog tsim nyob rau hauv daim ntawv ntawm seamless lug.Cov kav dej tooj liab yog siv hauv cov kav dej, HVAC, tub yees, kev kho mob roj, compressed cua tshuab thiab tshuab cryogenic.Ntxiv rau cov kav dej tooj liab tsis tu ncua, cov kav hlau tshwj xeeb kuj muaj.
Lub ntsiab lus ntawm cov kav dej tooj liab yog qhov tsis sib xws.Thaum cov khoom yog coiled, nws yog qee zaum hu ua tooj liab tubing vim nws ntxiv qhov hloov tau yooj yim thiab tso cai rau cov khoom yuav khoov tau yooj yim dua.Tab sis qhov kev sib txawv no tsis yog ib qho kev lees paub lossis lees paub qhov txawv.Tsis tas li ntawd, qee cov kav hlau ncaj nraim yog qee zaum hu ua tooj liab kav.Kev siv cov ntsiab lus no yuav txawv ntawm tus neeg muag khoom rau tus neeg muag khoom.
Tag nrho cov kav dej yog tib yam tshwj tsis yog qhov sib txawv ntawm phab ntsa tuab, nrog K-tube muaj cov phab ntsa tuab thiab yog li qhov ntsuas siab tshaj plaws.Cov kav dej no nominally 1/8 ″ me dua li cov kab uas hla sab nraud thiab muaj nyob hauv qhov ntau thiab tsawg los ntawm 1/4 ″ txog 12 ″, ob qho tib si kos (nyuaj) thiab annealed (soft).Ob lub phab ntsa tuab kuj tuaj yeem dov mus rau qhov nominal txoj kab uas hla ntawm 2 ntiv tes.Peb hom yog xim-coded los ntawm cov chaw tsim khoom: ntsuab rau K, xiav rau L, thiab liab rau M.
Hom K thiab L yog tsim rau kev siv siab xws li cua compressors thiab xa cov nkev thiab LPG (K rau hauv av, L rau sab hauv tsev).Tag nrho peb hom yog tsim rau cov dej hauv tsev (hom M nyiam), roj thiab roj hloov (hom L nyiam), HVAC systems (hom L nyiam), kev siv lub tshuab nqus tsev thiab lwm yam.
Cov kav dej, khib nyiab thiab lub qhov cua muaj cov phab ntsa nyias thiab qis qis.Muaj nyob rau hauv nominal ntau thiab tsawg los ntawm 1-1/4 "mus rau 8" thiab daj.Nws muaj nyob rau hauv 20-ko taw ncaj ntev, tab sis luv luv yog feem ntau muaj.
Tubing siv los hloov cov pa tshuaj kho mob yog hom K lossis hom L nrog cov kev xav tau tshwj xeeb purity.Cov roj siv los ua cov hlab ntsha yuav tsum tau muab tshem tawm kom tsis txhob muaj cov pa taws thiab ua kom cov neeg mob muaj kev noj qab haus huv.Cov kav dej feem ntau yog ntsaws nrog cov ntsaws thiab lub kaus mom tom qab ntxuav thiab brazed nrog nitrogen tshem tawm thaum lub sijhawm teeb tsa.
Cov kav dej siv rau cov cua txias thiab cov tub yees yog qhia los ntawm qhov tseeb sab nraud, uas yog qhov tshwj xeeb hauv pab pawg no.Qhov ntau thiab tsawg ntawm 3/8 "rau 4-1/8" rau kev txiav ncaj thiab 1/8 "rau 1-5/8" rau coils.Feem ntau, cov kav dej no muaj qhov ntsuas siab dua rau tib txoj kab uas hla.
Cov kav dej tooj liab muaj nyob rau hauv ntau yam alloys rau kev siv tshwj xeeb.Beryllium tooj liab tubes tuaj yeem ncav cuag lub zog ntawm cov hlau alloy hlau, thiab lawv lub zog qaug zog ua rau lawv muaj txiaj ntsig tshwj xeeb hauv kev siv tshwj xeeb xws li Bourdon hlab.Cov tooj liab-nickel alloy yog cov resistant rau corrosion nyob rau hauv dej hiav txwv dej, thiab tubing yog feem ntau siv nyob rau hauv marine ib puag ncig uas tsis kam mus rau barnacle loj hlob yog ib qho txiaj ntsig ntxiv.Copper-Nickel 90/10, 80/20 thiab 70/30 yog cov npe nrov rau cov khoom siv no.Cov yeeb nkab uas tsis muaj oxygen-dawb tooj liab feem ntau yog siv rau waveguides thiab lwm yam.Titanium coated tooj liab raj tuaj yeem siv rau hauv corrosive heat exchangers.
Raws li tau hais ua ntej, cov kav dej tooj liab tau yooj yim txuas nrog kev siv cua sov xws li vuam thiab brazing.Thaum cov txheej txheem no tsim nyog thiab yooj yim rau kev siv xws li kev siv dej hauv tsev, cua sov ua rau cov yeeb nkab kos rau anneal, uas txo qis nws qhov ntsuas siab.Muaj ntau txoj kev siv tshuab uas tsis hloov cov khoom ntawm cov yeeb nkab.Cov no suav nrog flare fittings, grooved fittings, compression fittings thiab laub fittings.Cov txheej txheem fastening tshuab no muaj txiaj ntsig zoo nyob rau hauv cov xwm txheej uas siv cov nplaim taws lossis cua sov tsis zoo.Lwm qhov zoo dua yog tias qee qhov kev sib txuas ntawm cov tshuab no yooj yim tshem tawm.
Lwm txoj kev, siv nyob rau hauv cov xwm txheej uas muaj ntau ceg yuav tsum tawm ntawm tib lub ntsiab yeeb nkab, yog siv cov cuab yeej extrusion los tsim ib lub qhov hluav taws xob ncaj qha rau hauv cov yeeb nkab.Txoj kev no yuav tsum tau soldering qhov kawg kev twb kev txuas, tab sis tsis tas yuav tsum tau siv ntau fittings.
